摘要： A service module that provides for discovery of one or more network interfaces connecting a prospective remote procedure call (RPC) client, facilitates the provision of RPC programs in a network including multi-horned systems. When a request for a network address to an RPC application providing an RPC program is received from the RPC client, the RPC bind daemon discovers from the module, using the client response address, over which interface(s) the client is accessible. The daemon then selects an address of a network path to the RPC application that the prospective client can access and returns the corresponding network address. The service module monitors the network stack for RPC get address requests and builds tables of client address entries with corresponding network interface identifiers. The entries are retired according to an aging policy. When multiple network paths to the RPC application are available, the service can be selected using a heuristic such as preferred interface, non-firewalled interface, least number of return path links or other criteria.

摘要： In a method for regulating network bandwidth in a virtualized computer environment, a computer having a hypervisor program receives a request from a first virtual client to transmit data. In response, the computer transfers the data from a memory of the first virtual client to a memory of a virtual server. The computer receives an error notification from a shared virtual network adapter of the virtual server, indicative of insufficient network bandwidth available to transmit the data. In response, the computer notifies the first virtual client that insufficient network bandwidth is available to transmit the data.

摘要： A network communication device can implement configurable network socket retransmission timeout parameters on a per socket basis. In one embodiment, it is determined, at a first network device, whether to define a network socket with a custom or a default retransmission timeout value to transmit data to a second network device. In response to determining to define the network socket with the custom retransmission timeout value, the network socket is defined with the custom retransmission timeout value, the data is transmitted to the second network device, and it is determined whether response data is received from the second network device prior to expiration of a time period associated with the custom retransmission timeout value. In response to determining that the response data is not received from the second network device prior to the expiration of the corresponding time period, the data is retransmitted to the second network device.

摘要： A method includes receiving a command to migrate a workload partition from a source machine to a target machine. The source machine and the target machine are communicatively coupled to a first subnetwork and a second subnetwork, respectively. The workload partition has a source network address defined by network addressing of the first subnetwork. The method also includes determining a socket connection providing network communication between the workload partition and a host. The method includes notifying the host that the workload partition is migrating from the source machine to the target machine, wherein in response to the notifying the host is on alert to receive, through a network tunnel communication, an identification of a target network address that is assigned to the workload partition after the workload partition is migrated to the target machine. The workload partition is migrated from the source machine to the target machine.

摘要： A computer implemented method, a tangible computer readable medium, and a data processing system intelligently propagate link status information received by a blade server to the various ports of an embedded multi-port switch. The link status of a switch port in an external switch module can be communicated to the operating systems of individual blade servers that are affected by that link status. When an external switch module is unplugged from a server blade chassis, the bus controller broadcasts a link down event, such as a link down interrupt, to the individual server blades where it is received by the embedded multi-port switch for those server blades. The embedded multi-port switch translates the link down interrupt into a hardware link down event, and forwards the hardware link down event to the other elements connected to the embedded multi-port switch.

摘要： A method, programmed medium and system are provided for preventing the denial of file system access to a plurality of clients accessing a NFS server. In one example, an NFS server is configured to listen on a server port. The server runs a separate daemon which “watches” client requests as they are received at the NFS server. The server processing system tracks the number of times a client sends consecutive TCP zero-window packets in response to a data packet from the server. If the number of zero-window packets crosses a user-defined threshold, then a routine is called to stop responding to that client using a backoff algorithm. When the server reaches a point where the number of available threads or any other relevant resource dips below a user-defined threshold, the server process starts terminating connections to the clients starting from the ones with the oldest entry in the table.

摘要： One embodiment for dynamically loading a service onto a node includes requesting, by a service requester, of a service from a service broker. Further, the method includes selecting, by the service broker, of the node among the nodes. Further still, the method includes re-booting, by the service broker, of the node based on the selecting, and then requesting, by the node, of an image from a TFTP relay agent for the service for the node. Yet further, the method includes querying, by the TFTP relay agent, for a type of the service from the service broker for the node, and then downloading of the image for the type of the service from a software repository accessed by the TFTP relay agent to the node. Finally, the method includes booting, by the node, to the image, informing the service requester that the service is ready for use, and using the service.

摘要： In a method for managing shared Ethernet adapters in a virtualized computer environment, a computer programmed with a hypervisor program receives a first request from a virtual client to transmit data. In response to receiving the first request, the computer programmed with the hypervisor program selects a first active virtual server from a first plurality of concurrently active virtual servers of the virtualized computer environment. The computer programmed with the hypervisor program copies the data from a memory of the virtual client to a trunk adapter of a first shared Ethernet adapter of the selected first active virtual server.

摘要： A method, system, and computer program product for a self-adjusting application heartbeat management process are provided in the illustrative embodiments. A first application receives from a second application, a response message in response to a heartbeat message. Information is identified in the response message usable for computing a delay in a future response message for a future heartbeat message, such that the information communicates to the first application a system condition existing in the second data processing system where the second application is executing. A response time is adjusted using the information to form a modified response time. The future response message is received after the response time.
